Identical to the O3_BASSPAURLINEAR class except the cross-sections are quadratically interpolated in temperature which is more in accordance with recommendations from the associated publications.
The table covers the wavelength range 245.0180 to 342.7800 nm in 1956 samples, of approximately 0.05 nm per step. The spectral resolution is better than 0.025 nm.
The Bass-Paur tables provide measurements at 6 temperatures:
- 203 K
- 223 K
- 246 K
- 273 K
- 276 K
- 280 K
This object quadratically interpolates cross-sections in temperature as given by the references.
